Abstract
The invention provides a photo bioreactor (1) comprising a vessel (10) containing an aqueous liquid comprising a photosynthetic culture and a light distributor (30). The light distributor has a surface (31) arranged to receive light (40) and a tapered surface (32) arranged to emit at least part of the received light. At least part of the tapered surface. (32) is submerged in the aqueous liquid comprising the photosynthetic culture. Light may be distributed efficiently in the aqueous liquid comprising the photosynthetic culture by relatively simple and cheap means. The reactor allows a high illuminated volume fraction.
Claims16
A photo bioreactor (1) comprising a vessel and a construction (300) comprising a plurality of light distributors (30),
- which vessel (10) comprises a body (60) comprising cavities (61) having tapered surfaces (62) which contain an aqueous liquid (20) that comprises a photosynthetic culture (21),
- wherein the light distributors (30) have a surface (31) arranged to receive light (40) and a tapered surface (32) arranged to emit at least part of the received light (40), at least part of the light distributor's tapered surface (32) being submerged in the liquid (20) that comprises said culture (21),
- wherein the light distributors (30) and the body (60) are in a configuration wherein the light distributors (30)
- (i) are at least partly arranged in the cavities (61),
- (ii) have substantially corresponding shapes, and
- the cavities are fluidly connected, and
- wherein, the tapered surfaces (62) of the cavities (61) are at a distance d2 from the tapered surfaces (32) of the light distributors (30), enabling a uniform flow of the liquid (20) between the cavities (61).
